Smart Segmentation combines the ability of a model-based and an atlas-based approach for semi-automated segmentation of organs at risk (OAR) and target volumes.
SteP 2 algorithm SeleCtion
The user can decide which algorithm to use for segmentation and can use a mix of Smart Detection or propagate from the expert case library.
SteP 1 expert CaSe SeleCtion
The expert case browser allows fast and intuitive selection of the most appropriate expert case, based on pathology and staging.
The user may filter the search based on tumor site, structures, expert case similarity and stage.
Smart Segmentation provides multiple educational resources and automation tools for immediate access to the user:

ExpERt CASE libRARy
The library includes contoured expert cases for many combinations of tumor sites and tumor classifications. The database covers lung, head and neck, breast, gastrointestinal, genitourinary and gynecological body sites.
SteP 3 deformation of StruCtureS from expert CaSe
Once the user selects “Start Segmentation,” selected structures are deformed from the expert case or segmented based on algorithm selected.
SteP 4 StruCture reView, edit and approVal
Once the segmentation process is complete, all delineat-ed structures are automatically displayed on the patient CT dataset allowing for side-by-side comparison with the reference image. Users can review and edit the result of the segmentation in any of the orthogonal views.
>
The anatomy atlas contains segmented CT data sets that are linked to detailed images and descriptions of the selected anatomy.
Semi-automated algorithm for lung tumor segmentation
Intended Use SummarySmart Segmentation® knowledge-based contouring provides a combined atlas- and model-based approach for automated and manual segmentation of structures, including target volumes and organs at risk to support the radiation therapy treatment planning process.
Important Safety InformationThe specific expert cases, commentary, and other information provided here are intended to provide scientific background and informative examples, and are not intended to provide medical advice or an endorsement of any particular radiation contouring or treatment procedure. The radiation oncology healthcare team is solely responsible for deciding whether a patient is a candidate for radiation therapy and how to provide and contour radiation therapy.
